Prepare Paper Plate

• Start this project on a sunny day just before noon.
• Use the pencil to poke a hole through the very center of the paper plate. Write the number 12 on the edge of the plate with a crayon. Using the ruler as a guide, draw a straight line from the number 12 to the hole in the center of the plate.

​Take Plate Outside

• At noon, take the plate and the straw outside.
• Put the plate on the ground and poke the straw through the hole.
• Slant the straw toward the line you drew.
• Now carefully turn the plate so that the shadow of the straw falls along the line to the number 12.

Fasten Plate to Ground

• Fasten the plate to the ground with some pushpins.
• Predict where you thinks that the shadow of the straw will be pointing in one hour.

Check Shadow Position Hourly

• One hour later, at one o'clock, check the position of the shadow along the edge of the plate and write the number 1 on that spot.
• Continue each hour predicting the position and then checking and marking the actual position and time on the edge of the plate.​
